Committed to the energy transition

日日夜夜撸To support the energy transition, GM&T brings environmentally friendly solutions to ?the clean energy market with hydrogen energy and Bio- Natural Gas for vehicles, refrigerated transport using nitrogen, but also the treatment and injection of biogas into the energy grid.

Hydrogen energy

日日夜夜撸Hydrogen offers a number of benefits for clean transportation. Used in a fuel cell, it combines with oxygen from the air to produce electricity, with water as the only byproduct. Hydrogen does not generate any pollution at the point of use: zero greenhouse gas, zero particle and zero noise. This energy brings a concrete response to the challenges of clean mobility in urban areas and helps to improve air quality.

Air Liquide has already designed and installed more than 120 hydrogen stations worldwide, including almost 58 operated by the Group. The stations are located in Europe (France, Denmark, Netherlands, Germany and Belgium), Asia (Japan), North America (United States and Canada), and the Middle East (United Arab Emirates).

日日夜夜撸Air Liquide also supports the growth of the Paris hydrogen taxi fleet, Hype. This fleet, deployed in late 2015 by the start-up STEP (Société du Taxi électrique Parisien) in partnership with Air Liquide, already counts 100?hydrogen-powered vehicles and plans to deploy a total of 600 by the end of 2020.

Biomethane and circular economy

Thanks to its membrane technology, Air Liquide has developed an expertise covering the entire biomethane value chain, from biogas supply and purification for biomethane production to its final usage by the client with bio-NGV (Natural Gas for Vehicle) or clean multi-energy stations (NGV, bio-NGV, liquid nitrogen for cold transportation) or for domestic grid injection.

The biomethane value chain contributes to the development of the circular economy, thanks to the association of actors working together locally for the energy transition.

Bio-GNV is a clean and renewable energy that reduces CO2 emissions by 90%, particulates by 85% and noise by up to 50% compared to diesel.

Biomethane is produced from Air Liquide's purification and liquefaction technologies that make it possible to recover all biogas (organic waste, agricultural waste, sewage sludge, etc) and inject it into the gas network, as well as produce clean fuel for vehicles or renewable hydrogen.

Air Liquide operates nearly 70 biomethane stations in Europe, mainly in France, Sweden, Norway and the United Kingdom, and 12 biomethane production units in the world: Europe, China and the United States. Therefore, Air Liquide is the world leader in the production of biomethane with a capacity of about 90 MW, or 800 GWh per year.

Player of deep tech

日日夜夜撸As a player of the deep tech sector, Air Liquide commercializes technologies dedicated to Space, Aerospace and scientific exploration.


Air Liquide has established its reputation in the field of space thanks to its expertise with rocket launchers (ground resources and Ariane launchers), in the design of cryogenic equipment for satellites as well as space exploration (MTG, Herschel, Planck, Melfi, Curiosity, ExoMars, etc.). Air Liquide continues to develop new technologies for the future Ariane 6 launcher or for electric propulsion for satellites and its projects in connection with space exploration, like the generation and storage of energy and life support in a simulated lunar environment.


Thanks to its expertise in gas separation and control techniques, Air Liquide contributes to these developments日日夜夜撸 by designing systems for the generation, storage, and distribution of gases, for both onboard and ground applications.

Extreme cryogenics

Expert in cryogenics (extremely low temperatures) and in gas engineering, Air Liquide designs and supplies cold production, liquefaction, and cryogenic fluid storage and distribution systems for laboratories and large scientific equipment.
Air Liquide is recognized as a partner of scientific research.

日日夜夜撸With this expertise, Air Liquide has developed a refrigeration and liquefaction technology based on the physical principle Turbo-Brayton that allows the re-liquefying natural gas evaporation of LNG tankers transporting Liquefied Natural Gas (LNG), in order to avoid any emission of greenhouse gases during transportation.

The cryogenic equipment proposed by Air Liquide, based on this technology, offers the opportunity for shipowners and charterers to improve the energy efficiency of the LNG cargo of their LNG carriers, as well as natural gas powered boats, while meeting regulation of the marine industry on the limitation of the release of greenhouse gases. This technology, first developed for space, can also be adapted to other sectors and for other gases, for example to liquefy biomethane for road transport of goods.

Maritime activity

Air Liquide also supplies gases for players in of the maritime sector and provides logistics for cryogenic transportation by sea of value added molecules, such as helium.

日日夜夜撸As world leader within the maritime industry, our multimodal solutions for logistics and cryogenic transportation of high value-added molecules, such as helium, argon, carbon dioxide and liquefied natural gas, provide our customers with service they can rely on.

Aligning with our climate objectives, we focus on energy related businesses within the maritime environment, including renewable solutions日日夜夜撸 such as offshore windmills, emission reduction with membrane offers, and improved platform maintenance with dry ice blasting.

With a fleet over 850 ISO containers, we provide logistic activities by sea日日夜夜撸, based on cryogenic transport, that reach our affiliates and customers across the world. Using cutting edge digitalization, we are able to optimize our supply chain and create value for our customers.
